X1 and X2 are two independent Gaussian random variables each with mean zero and unit variance. Let
Y1 = 2X1 + X2 + 3 (1)
Y2 = X1 ô€€€ X2 ô€€€ 1 (2)
Find the joint probability density function of Y1 and Y2.
Find the nonzero value of ω for which the expression for Z(ω) given is purely real. Give your answer as a function of R, L, and C.
The waveform output by the signal generator in part (b) is changed so that the rectangular pulses have the same width but no longer are periodic. They occur at random intervals of time. Explain in words how the display on the spectrum screen would..
